Luz Cumba García (Mayo Clinic): Decoding Brain Tumors with Extracellular Vesicles

Описание: http://www.iBiology.org

Solid tumors, such as those in the brain, can be deadly when they expand or spread to other parts of the body. Before they spread, tumors send out molecular messages within small membranous structures known as extracellular vesicles (EVs). The proteins and small non-coding RNAs inside EVs can help tumors evade the immune system and seed new sites of growth. In this Share Your Research talk, Dr. Luz Cumba García describes her thesis research on extracellular vesicles released by aggressive brain cancers called glioblastoma. Dr. Cumba García’s work helps scientists understand the EV profiles of different glioma subtypes, as well as how the messages inside EVs help them shut off the immune system.

Speaker Biography: Dr. Luz M. Cumba García is an immunologist with 13 years of experience working at the intersection of immunology, public policy, and diplomacy. Luz is currently a policy advisor at the government relations firm Lewis-Burke, LLC, where she leverages her biomedical research background to bolster issue expertise of the National Institutes of Health (NIH) and other agencies within the Department of Health and Human Services (HHS). Luz is a proud Puerto Rican! She recently earned her Ph.D. in Immunology from Mayo Clinic Graduate School of Biomedical Sciences in Rochester, MN. Her thesis dissertation focused on analyzing small particles in the blood called “extracellular vesicles” shed from glioblastoma (GBM) brain tumors as “liquid biopsies” to predict tumor growth and monitor treatment outcome.
